Do all devices have problems connecting to the 2.4Ghz radio?
What wireless modes and settings are you currently using on the 2.4Ghz radio?
Yep, every single device in the house has issues with the 2.4 GHz band. Whenever I change a setting on it, it works fine for a bit, but then it slowly starts to degrade. I don't even have that many devices connected to it, up until now it was only 2 that actually used it on a regular basis.
Settings:
Wireless is always enabled
Mixed 802.11n and g
Auto Channel Scan enabled
Transmission rate set at best (auto)
Channel width set at 20/40 (auto)
Status is visible
Uses auto (WPA/WPA-2) and TKP/AES
